I just updated
michelf vtable benchmarking to D2, and checked DMD stats on my Linux box.
[shd@magdalene vtable-tests]$ uname -o -p -m
x86_64 AMD Phenom(tm) II X2 550 Processor GNU/Linux
[shd@magdalene vtable-tests]$ gdc --version
gdc (GCC) 4.5.1 20100731 (gdc 0.30, using dmd 2.054)
[shd@magdalene vtable-tests]$ dmd
DMD64 D Compiler v2.053
[shd@magdalene vtable-tests]$ gcc -v
gcc version 4.6.1 (GCC)
So, here is the output:
[shd@magdalene vtable-tests]$ ./test-dmd.sh
